I'm a bit late on reporting this, sorry. Thanks to Roberto for posting this information to wallace-l

This September Einaudi is going to publish Questa è l'acqua (This is Water), in Italian.

Interesting is that this is not just This is Water, but also, Planet Trillaphon, Solomon Silverfish, Northampton, Other maths, and Crash of '69. It will include a preface by Don De Lillo and it translated by Giovanna Granato (she already translated Oblivion).
